Plant models as teaching aids

Separable SOMSO plant models - an ever expanding collection. Nearly every botanical SOMSO model has been developed in cooperation with Prof. Dr. W. Weber.

	BoS 17 - Deciduous Leaf Enlarged 700 times, made in SOMSO-Plast®. After Prof. Dr. W. Weber. Transverse and longitudinal sections showing the microscopic formation. Model in one piece. On a green base plate, with explanatory key.

	BoS 17/1 - Section through the Leaf of the Helleborus Enlarged 700 times, made in SOMSO-Plast®. After Prof. Dr. W. Weber. The model shows the upper epidermis with cuticula, the assimilation network (separated into pallisade and parenchymatous cells with cytoplasmic lining) and the lower epidermis with stomates. Model in one piece, on a stand with green base and explanatory key.

	BoS 17/2 - Stomate of the Underside of a Christmas Rose Leaf Helleborus niger, many times enlarged, made in SOMSO-Plast®. After Dr. Gerlach, Botanical Institute Erlangen. Shown are guard cells, accessory cells, stomate respiratory cavity. One half of the model shows the stomate, the other the function can be demonstrated symbolically. Model separates into 2 parts.

	BoS 17/3 - Maize Leaf in Longitudinal and Cross Section Zea mays, model enlarged approx. 450 times, made in SOMSO-Plast®. After Prof. Dr. W. Weber. The model shows the special leaf structure of a C4 plant. The vascular bundles are enclosed by a sheath in ring form. The chloroplasts of the sheath correspond with the biochemical work appropriation in the case of photosynthesis and are clearly larger than the chloroplasts of the mesophyll cells. The vascular bundles are interlinked with each other by transversal anastomoses. Model in one piece, on a stand with green base and description key.

	BoS 20/2 - Root Tip of a Monocotyledonous Plant in Longitudinal and Cross Section Barley, Hordeum vulgare, model enlarged approx. 200 times, made in SOMSO-Plast®. After Prof. Dr. W. Weber. The root cap encloses the apical meristem. The tissues of the root body are formed by various initials: rhizodermis, root bark and central cylinder. Model in one piece, on a green base, with description.

	BoS 21 - Anatomical Structure of Pine-Wood Pinus silvestris, model enlarged approx. 350 times, made in SOMSO-Plast®. After Prof. Dr. W. Jung. The model shows the anatomical structure of pine-wood in various sections: transverse, radial longitudinal and tangential longitudinal through the cambium zone, original wood, secondary wood and bark. Showing all the elements of the wood structure. Model in one piece, on green base with explanatory key.

	BoS 21/1 - Section through a Two Year Old Twig of the Lime-Tree Tilia sp., model enlarged 350 times, made in SOMSO-Plast®. After models and drawing by Prof. Dr. W. Jung. Sections through the dispersed porous type of wood show all the elements of the wood structure (transverse, longitudinal, radial and tangential). Model in one piece, on a green base with explanatory key.

	BoS 21/2 - Needle leaf of the Austrian pine, pinus nigra longitudinal and cross section, magnified approx. 300 times. Model according to Prof. Dr. W. Weber. Dismantable in 3 parts.

	BoS 22 - Open Collateral Conducting Bundle of a Dicotyle Plant Enlarged approx. 550 times, made in SOMSO-Plast®. After Prof. Dr. W. Jung. Model in one piece, on a green base with explanatory note.

	BoS 22/3 - Section through the Peripheral Part of a Monocotyle Stem Maize, Zea mays, model enlarged approx. 550 times, made in SOMSO-Plast®. After Prof. Dr. W. Jung. Model in one piece, on a green base plate with explanatory key.

	BoS 22/4 - Section through the Stem of a Year Old Dicotyle Plant Lime-tree, Tilia sp., somewhat simplified, model enlarged approx. 125 times, made in SOMSO-Plast®. After Prof. Dr. W. Jung. On a green base with explanatory key. Model in one piece.

	BoS 22/4-E - Section through the stem of a year old dicotyle plant Lime-tree, Tilia sp., somewhat simplified, model enlarged approx. 125 times, made in SOMSO-Plast®. After Prof. Dr. W. Jung. On a green base with explanatory key. Model in one piece.

	BoS 22/5 - Young Root of the Buttercup Ranunculus acer, sectional model, model enlarged approx. 300 times, made in SOMSO-Plast®. After Prof. Dr. W. Jung. Model in one piece, on a green base with explanatory key.

	BoS 22/5-E - Young Root of the Buttercup ranunculus acer Sectional model, model enlarged approximately 300 times, made in SOMSO-Plast®. A per Prof. Dr. W. Jung and overworked by Prof. Dr. W. Weber. Model in one piece, on a green base.

	BoS 22/6 - Cross-Section through the peripheral section of a stem (Caulis) Enlarged approximately 450 times, made in SOMSO-Plast®. After Prof. Dr. W. Weber. Model in one piece, on a green base.

	BoS 22/7 - Root of shallot bulb Allium ascalonicum, sectional model, model enlarged approx. 350 time, made in SOMSO-Plast®. After Prof. Dr. W. Weber. Model in one piece, on a green base with key.
